DEVICE FOR THE' WET TREATMENT OF TEXTILE PRODUCTS Filed Nov. 8. 1-930 IPatented Nov. 29, 1932 UNITED STATES PATENT orrlce DEVICE FOR THE WETTREATMENT OF TEXTILE PRODUCTS Application filed November 8, 1930, SerialNo This invention relates to a device for the wet treatment of textileproducts.

Devices for the wet treatment of suspended textile products, forinstance, in the 5 form. of an endless hand (such as fibres twisted intostrands or hunks) are known,

wherein the vertically extending parts of the band are pessed loetweenspray devices to which the treatment liquid is fed by circula- 19 tionfrom u reservoir. Thereby the textile products are freely suspended forinstance from o drum alcove the reservoir. The said drum is rotated icymeclicnicel means to obtain it liquid as uniform es possible.

The object of the invention is to provide e rotational movement of thedrum by causing only one half of the hunks or the like to be subjectedto the liquid treatment. this means a considerable simplificetion oi thedevice is accomplished, inasmuch as mechanical means for causing therotation oi? the drum are avoided.

In the accompanying drewing e construe: tionol form oi invention isillustruted by way oi"- exemple only wherein it shows a sections? sideeievetion of the device;

Fig. 2 is u vertical tion of the device, and

Fig. 5 shows c section of e deteil.

The textileproducts A in the form of an endless bend are suspended srotetaloly mounted drum 1. Titles verticul portions of the hand onepessed between spray devices 2, 2 end 3 3 tespectively. The treatmentliquid is c-eused to circulate from a reservoir l through a. centrifugalpump 5 to the spray devices 2, 2 end 3, 3 and loo-cl; into thereservoir. In the circulating conduit a control means in the shops of:vvalve 6 is included which as will be seen in Fig. 3, enables toselectively operate the spray devices 2, 2' for the left hood verticalportion of the bend and 3, 3 for the right hand portion of the bend.Above the reservoir l a tank 7 is provided in which the lower part ofthe hand A is continuously submerged. By submerging the band it isimparted on uplift which re 1 ouces the tension in the fabric andprevents .494,426, and in Germany November s, me.

without causing unequal colouring in .the

goods the latter not being submerged in the 65 reservoir, but in aspecial tank.

As only the spray device associated with the one vertical portion ot theband is operative and the other inoperative this portion is treated withan excess of liquid which flows downwardly alongside of the respectiveportion, thus automatically causing the band to move in thedirection'oi'this fiowand inducing the drum to turn. The uplift actingon. the goods submerged in the tank 7 substantielly contributes toassist the movement of the bend. @n reversing the control means spra ingof theotl'ier vertical portion of the loan is effected and thus movesthe band in the opposite direction.

Therefore with tne simplest meens the endless loend is caused to movepast the spray devices which, heretofore, was only attained by the aidof special mechanisms, such as means for rotating the drum or oucketwheels C for moving the bend. In this manner the invention is bound tobring about a substantial technical advance in the ert of dyeing.

1 claim:

i. in s device for the wet treatment ofsuspended textile products with acirculating liquid u combinetionof a freely rotatable member forsuspending the textile products therefrom in an endless band, and ameans for contesting e liquid with said textile products suspended onone side only of said rotateble nruemloer. whereby the rotatable memleerwill turn due to the greaterweight oi:- the absorbed liquid.

2. in e, device for the wet treatment of suspended textile products icymeans of a circulating treatment liquid, in combination. a rotatablemember for suspending the textile products therefrom in the form of'anendless bend, a spray device for each vertical portion of the suspendedproducts adapted to project the treatment liquid thereon, anddistributing means to render operative the spray device acting on onevertical portion and the other spray device inoperative to cause anautomatic rotation of said memberw 3. in e, device for the wet treatmentof suspendlei textile products by means of n oinculetin treatmentiiquioi, in eomiiination e roteteb e d for suspending the textileproducts in form of en eniiess bend there-- from, an; spray device foreach vertical portion of the enspendedl pxro&ucts edinpted to projectthe treatment liquid! thereon e. i'eeewoii El, conduit and e nmp betweensaid reservoir and saidl spray evices, end control means in said;conduit for seiectivei ooectin seiol spray devices to cause sei'treetment iquidl to circniete through said conduit and either one ofsaid spray devices in en amount that the respective vertical portion ofthe sue= pended products is moved downwards by gravitation endl seidiroteteibie drum entomaticaiiy tuned,
